John Harrison, the English watchmaker who invented the marine chronometer in 1761, was born on this day 325 years earlier. His path of invention today allows us to accurately determine longitude on the high seas, he was the one to revolutionize and contribute to the very primary development of navigation.

We collect the memories on John Harrison's 325th birthday.

Even as Harrison has had the basic education from schools in Yorkshire, England, he was able to make such an astonishing invention. The most famous '5 watches' made by Harrison are named modestly after him as Harrison 1, 2, 3, 4, 5.

He was a son of a carpenter who worked as guardian of a country estate and the turning point in his life was when he got his hands on a practical mechanics' book and was fascinated by it. He studied it carefully, made notes and took as much as he could from the book and used what he learnt.

Harrison started his career when he was 20 by building his first pendulum clock that was completely made out of wood when he hasn't even practised as a carpenter ever.

The watches made by John Harrison are still alive, displayed at the National Museum in Greenwich.
